This is a map by me, based on the game S.T.A.L.K.E.R.: Shadow of Chernobyl. It is ported models/textures from the game mostly, you play as Loner attacking a Military base somewhere in the Zone. Look out for some hungry bloodsuckers in the area.
The map is surrounded with radiation so don't go far away from the borders of the Military base.
GSC Game World said that it is possible to use their models as long as credit is given to them.

Pros: Looks great and S.T.A.L.K.E.Rish.
Cons: none.
Improvements: You should make it work for gmod9.
Notes: Gmod9 cant run it. The map starts up and i can walk a couple of steps, but then hell of a lot of lag comes and the game crashes. But judging from the screenies it is awesome. If this worked for gmod9 it would be perfect.
